Computer-implemented techniques for viewing a recorded presentation are described. The techniques include receiving by one or more computers a request from a user to view a recorded presentation, retrieving, by one or more computing systems, a segment of the recorded presentation that is comprised of plural segments and information specifying times of occurrences of trigger events associated with corresponding segments in the recorded presentation, retrieving by the one or more computers private information of the user relevant to a first segment of the recorded presentation based on a first trigger event, generating, by the one or more computing systems, a re-cast first segment of the recorded presentation, with the re-cast first segment including the private information of the user, and sending by the one or more computing systems, the re-cast segment to a computing device associated with the user.
